Stacey Allaster has become the US Open’s new tournament director, the first woman to hold the job at the New York Grand Slam event.

Allaster is a former CEO of the WTA women’s tour and has worked at the US Tennis Association since 2016.

She has been responsible for many changes, including the serve clock and warm-up clock and lobbying for coaching to be allowed during matches.

She will stay as the USTA’s chief executive of professional tennis.

Allaster replaces David Brewer, who became the Open’s tournament director in 2012. The USTA said last year that Brewer would be stepping down after the 2019 Open.
